At present, many families have installed aluminium alloy doors and
Windows when decorating, in beautification environment also bring a
few inconvenience and hidden trouble, such as aluminium material
deformation, door window cannot push pull even window fan falls
etc. Many buyers write to ask why, how to check the quality of
aluminum door and window, this article puts forward some
Suggestions, for your reference.

China's construction of aluminum products started in the early
1980s, and the speed of development is the first in the world, from
aluminum profiles, aluminum doors and Windows, aluminum curtain
walls to the curtain wall of the hidden glass. The main reason for
the rapid development of aluminum products in China is that the
introduction of aluminum and aluminum doors and Windows production
lines in more than a dozen countries in foreign countries and the
director of the countries in the world, which is one of the
important reasons for the absorption and absorption of the
products.

Due to the rapid development, also produced many problems: such as
the national architectural aluminum manufacturer has increased
rapidly, production is too big, "porridge more monk less," the vast
majority of aluminum factory production can not meet the design
index, now production can meet the design ability for half of the
factory, aluminum sales are very competitive. In the past two
years, the construction industry has developed rapidly, but the
demand for aluminum doors and Windows is far less than that of
aluminum. So in the aluminium industry, production is more than
sales, aluminum doors and Windows production energy is very large,
although aluminum door and door requirement increases quickly, but
aluminum door window industry still is "the congee is multi-monk
little". Some aluminum Windows and doors factory in order to get a
task, to get the contract, by hook or by crook, cheat users
deliberately driving engineering quotation, to get the optimal
contract with carrier again after generations, false and true,
still need to achieve the purpose of making money, don't only
pursue cheap, regardless of the quality, be deceived.

How to choose aluminum profile

Domestic a lot of alumina factory, because of various condition
different, the aluminous material qualitative difference that
produces is very big, the sale price also has a big difference,
each ton of noble can be less than 4 ~ 5 thousand yuan. The
domestic price of aluminum ingots is basically the same. In the
process of processing, there is such a large difference in price
difference, and there is a big difference in quality. Aluminum
quality depends on the following several factors: 1. The alloying
elements: 6063 alloy is magnesium aluminum silicon alloy as the
main elements, each element has a range of content, magnesium price
is high. Some manufacturer in order to reduce costs, the magnesium
consumption to a minimum allowing content. What's more, the content
of magnesium is lower than the allowable minimum content. There is
also a factory in the alloy with waste wire and waste pot waste
aluminum pot, basically not 6063 alloy. The mechanical strength of
the aluminum profile is very low, so it can be bent easily with
both hands. It is commonly known as "noodle" as soft. This is one
of the reasons why aluminum can be cheap for thousands of yuan.
Formal aluminum material in the preparation of alloy composition,
has the internal standard, is within the scope of the various
elements, GeChang have their own smaller range, aluminum,
magnesium, and silicon is strict proportion, GeChang has its own
data, secret each other. There is a qualified formulation of the
alloy to guarantee the quality, otherwise the quality will not be
able to be processed.

Guangdong yong long aluminum co.,LTD. is located in Lishui
District, Foshan City, Leping Group on the 10th, the company was
founded in 1997, is set aluminum profile research and development,
production and sales as one of the integrated large-scale aluminum
enterprises, "Hong surplus" brand. Strong comprehensive strength
and quality of service, so that Wing Lung "Hong Ying" selling all
over the country, exports to the United Kingdom, the United States,
Australia, Canada, Russia and other countries.

After years of development, the company passed the ISO9001: 2000
quality system certification, the international standard product
certification. Yonglong Aluminum has won the "Guangdong Province
Famous Brand", "Guangdong Province Famous Brand", "ISO14001

products "and other certificates. Companies adhere to the
scientific concept of development, by strengthening the
comprehensive management and increase innovation, and continuously
enhance the energy-saving emission reduction enterprises to
accelerate into the environment-friendly modern enterprise list.

The company insisted: "unity and progress, pioneering and
